SPECIFICATION formingjoart of Letters Patent N o. 670,685, dated March26, 1901.

Application tiled June 11,1900. Serial No. 19.860. .No model-l To (LZZwhom, 11a/Ly concern:

Be it known that we, OLE OLSEN and HAG- BART EvENsoN, citizens of theUnited States, residing at Belview, in the county of Redwood and Stateof Minnesota, have invented certain new and useful Improvementsin Corn-Planters; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same. A

Our invention has for its object to provide an improved corn-planter;and to this end it consists of the novel devices and combinations ofdevices hereinafter described, and defined in the claims.

The invention isillustrated in the accompanyingdrawings, wherein likecharacters indicate like parts throughout the several views.

Figure 1 is a plan View of the improved machine, some parts beingremoved. Fig. 2 is a rear elevation of the machine. Fig. 3 is a sideelevation of the same. Fig. 4: is a vertical section approximately onthe line fc4 m4 otl Fig. 1. Fig. 5 is a detail, on an enlarged scale, insection on the line @c5 x5 Vof Fig. 1. Fig. 6 is a similar view to Fig.5, but in section on the line m6 x6 of Fig. l, some parts being brokenaway. Fig. 7 is a horizontal section on the line @c7 :1:7 of Fig. 5.Fig. 8 is a bottom plan View of one of the shoes. Fig. 9 is a plan viewof one ot' the seed-magazines, the cover thereof being removed. Fig. 10is a horizontal section approximately on the line w10 m10 of Fig. 6, andFig. 11 is a horizontal section taken approximately on the line mum ofFig. 9.

The machine or wheel frame 1 is pivotally mounted by means of bearings 2on a driving axle or shaft 3, on the ends of which the traction-wheels 4are mounted, being preferably connected therewith by pawl and clutchdriving devices. (Not shown, but of any ordinary construction.) Theforwardly-projected portions or beams oi"A the main frame 1 arepivotally connected by brackets 5 to the forward or intermediate portionof a transversely extended supplemental or runner frame 6. Thesupplemental or run-ner frame 6 is provided with a pole 7, which isrigidly connected to the intermediate portion thereof, as best shown inFig. 1.

The planting-shoes, to be hereinafter described, are mounted on orconnected to the supplemental frame 6, and to raise and lower the saidsupplemental frame, together With the part-s carried thereby, alifting-lever 8 is pivoted, as shown, to the rearwardly-projected endoi' the pole 7 and to a lock-segment 9 by means of a pin or stud 10. Theliftinglever 8 is provided with a hand operated latch 11 for cooperationwith the lock-segment 9, and the lower end of the said lever ispivotally connected to the main frame 1, as shown, by a link and eye l2.(See particularly Figs. 1 and 4.) As the outer end of the pole will besupported bythe draft-animals When the machine is in operation, it isevident that the supplemental frame may be raised and lowered and heldin different vertical positions by means of the latch-levers 8 11 andlock-segment 9.

The dri vers seat 13 is shown as supported from the rear portion of themain frame 1. To keep the peripheries of the traction-wheels clean,Scrapers 14 on a common shaft 15, mounted in the main frame 1, areprovided. A spring 16, connected at one end to the main' frame 1 and atits other end to a short arm 17 of the shaft 15, normally holds theScrapers in contact with the Wheels 4.- Another arm 1S on the shaft 15is connected by a link 19 to a foot-lever 20, pivoted at 21 to one sideof the mainframe, with its upper end in position to be engaged bythefoot of the driver seated on the seat 13. By pressing on the upperend of the lever 20 with the footv the Scrapers 14 may be thrown intoinoperative positions.

The marking devices (one at each side of the machine) are connected oneto each end of the supplemental frame 6, and as these parts, as Well asthe cooperating planting devices, are in duplicate they will bedescribed in the singular. A long counter-shaft 22 is mounted insuitable bearings in the supplemental frame 6, with its ends termin-atedapproximately at the ends ofthe said frame 6.

This shaft receives its motion from a sprocket chain 23, which runs overa driven sprocket. 24 on the said shaft 22 and over a drivingsprocket 25on the driving-axle 3. The driving-sprocket 25 is loose on the `shaft 3and is provided with a half-clutch 26, with which a IOO coperatinghalf-clutch 27, mounted to slide on but to rot-ate with the shaft 3,cooperates. A spring 28 puts the half-clutch 27 under strain to engagethe half-clutch 26. The sliding half-clutch 27 is adapted to be movedand held in eit-her an operative or an inoperative position byalatch-lever 29, pivoted to a latchseginent 30, which in turn is rigidlysecured to the main frame l.

Of the parts'of each marking device the numeral 31 indicates anapproximately V- shaped frame which is hinged at 32 to the adjacent endof the supplemental frame 6.

33 indicates a shaft journaled iu the outer portion of theframe 3l andhinged to the adjacent end of the driven shaft 22 by a knuckle-joint 34,which is located in transverse line with the pivots 32 of the said frame31,

so as to permit said frame 31 to be raised.

while the machine is in action. At its outer end the shaft 33 isprovided with a wheel 35 and with a radially-projected marker 36.

To enable the operator from his seat to raise and lower the markingdevices, or either block 49.

of them, at will, a latch-lever 37 and coperating latch-segment 38 isprovided at each side of the machine, and each lever is connected by acord or flexible connection 39 to the outer end of the cooperating frame31. The cord 39 is passed over a guide-sheave 40 on the main frame 1 andovera guide-sheave 42 on the upper end of an arm 43, pivoted to thesupplemental frame 6 at 44. The outward movement of the arm 43 islimited by the stop 45 on the supplemental frame. For a purpose to behereinafter noted the lever 43 will be moved inward when the frame 33 israised, and to accomplish this a cord or connection 39 is provided witha stop 46, which when the frame 33 is raised, .as shown at the left inFig. 2, positively forces thesaid arm 43 inward. f

A planting-shoe with coperating planting mechanism is, as alreadyindicated, located at each side of the machine. Such plantingshoe 47works just outside of the tractionwheel at that side of the machine andis pivoted to the forward portion of the supplemental frame 6, as shownat 48. The rear portion of the shoe 47 is divided or flanged andprovided with a transversely-extended spacing-block 49 and with a hollowverticallyextended feed leg or spout 50, the lower end of which opens ator just above the inclined rear portion of the block 49. A cut-off bladeor dropper 51 is pivoted between the rear flanges of the shoe 47 for'coperation with the Alink 52 connects the upper portion of the blade 51to the lower end of a triplever 53, which is pivoted between the sidesof the shoe and is subject to a spring 54, connecked thereto and to adrag-bar 55, one end of which is secured to the side of the shoe 47 andthe other end of which is pivoted to the supplemental frame 6, in linewith the shoepivots 48. Preferably there are two bars 55 for each shoe,so arranged as to prevent un- `purpose to be hereinafter noted.

4 due lateral movements of the said shoe. The

spring 54 tends to hold the cut-off blade 51 in its closed position,(indicated at Fig. 5,) in which position it coperates with the block 49and the sides of the vshoe to hold the kernels of corn dropped throughthe leg 50.

Just above the shoe 47 the shaft 22 is provided with a crank' portion56, one side of which crank has a cam extension 57, for a Working on thecrank portion 56 is a box or bearing 58, which is mounted to slidebetween the prongs of a bifurcated link 59, the lower end of which ispivoted between the sides of the shoe 47. A spring 60 is compressedbetween the box 58 and the lower end of the link 59, tending to forcethe box upward, or, rather, Y

thelink downward. A pin 6l, passed through the upper ends of the prongof the link 59, limits the downward movement of said link, and hence ofsaid shoe 47.

The shoe above described is normally carried above the ground; but ateach hill to be planted it is forced downward and into the ground by themovement of the crank 56. While the shoe is forced into the ground,shown in Fig. 6, the cam projection 57 strikes the upper end of thetrip-arm 53, and through the connection 52 moves the cut-off blade 5linto its open position, (indicated in Fig. 6,) and thus drops the cornpreviously held thereby, as shown in Fig. 5.

Secured by a shelf or bracket 62 on the supplemental frame 6,immediately over the cooperating shoe 47, is a seed magazine orreceptacle 63, provided with a disk or rotary bottom 64 and preferably,also, with a lid 65. The rotary bottom has aplurality of perforavtions66, which are adapted to be brought successivelyinto registration with aperforation 67 in the bottom of the shelf 62, immediately above theupper end of the shoe-leg 50. As shown, a sleeve 68, secured to thebottom of the shelf 62, surrounds the said perforation 67 and is adaptedto telescope into said shoe-leg 50 when the shoe is raised, as shown inFig. 5. The seed-magazine 63 is provided with an inwardly-projectingsegmental section 69, formed with an upwardlybulged channel 70, whichoverlies the particular perforation 66 of the bottom 64, that stands inregistration with or in the vicinity of the perforation 67. Within theraised portion 70 is a spring-cam or cut-off 7l, which directs thekernels of corn which may project from the perforation or pocket 66downward through the line-perforations 66 67. In the constructionillustrated the magazine 63 IIO is supported from the shelf 62 by aplurality shelf 62 engages in succession said notches to temporarilyhold the rotary bottom with one or the other of its perforations orpockets G6 alined with the perforations 67 in the shelf 62.

A step-by-step movement is given to the rotary bottom under the advancemovement of the machine from a segmental gear77, secured on the drivenshaft 22. The segmental gear 77 engages intermittently with anintermediate gear 78, suitably journaled on one of the depending sidesof the shelf 62, as best shown in Fig. 5. This gear 78 meshes withgear-teeth 79 on the under peripheral portion of the rotary bottom 64.The segmental gear 77 has only enough teeth to cause byits passingengagement with the intermediate gear 78 the rotary bottom (54 to movethe angular distance between its perforations or pockets 66, and thismovement is arranged to take place while the shoe 47 and leg 50 areraised, as shown in Fig. 5, at which time the kernels of corn requiredfor one hill are dropped through the leg 50 onto the block 49 and cutoffblade 5l, from whence, as already stated, they will be deposited in theground while the said shoe is forced downward, as indicated in Fig. 6.

The action of the marking device or checkrow marker will be readilyunderstood by all persons familiar with this class of mechanism. It is,however, evident that the marker on but one side of the machine will beused at one time. I-Ience that mechanism on the inoperative side of themachine should loe elevated and remain idle.

The outer ends of the shaft 22 instead of being rigid are looselyconnected, as shown at 8O in Fig. 2, the sections being connected byhalf-clutches 8l 82, mounted to rotatewith their respective sections andthe former to slide on the loose outer section 22L to and fromengagement with the cooperating halfclutch 82. A spring 83 tends to holdthe halfclutch 8l in engagement with the half-clutch 82; but the saidhalf-clutch 82 is adapted to be moved into an inoperative position bythe oscillation of a rock-shaft or rod 84, mounted in suitable bearings85 on the supplemental frame 6 and provided with a semicirculardepending crank-section 86, as shown in Figs. l and 2, which engages agroove 87 in the said half clutch 8l. The above releasing movement ofthe rock-shaft 84 is automatically produced when the marking-wheel is`raised, as indicated in Fig. 2 and as already described, by theengagement of the arm 43 with a vertical projection 88 at the rear endof the said rock-shaft 84. The action of the machine as a check-rowplanter should be understood from the foregoing description. The machineis, however, capable of use for planting fodder-corn, in which case thecorn should be planted in rows having very closelyspaced hills. For thislatter operation a supplemental segment 89 is applied to the segmentalgear 77, as indicated by dotted lines in Fig. 5. As shown, thissupplemental gearsection 89 has two groups of teeth, which, with theteeth of the gear 77, make a gear having three groups of teeth adaptedto move the ro'tary bottom of theseed-magazine three steps of movementfor each rotation of the shaft 22. In this action the link 59 should berendered inoperative, which may be done by disconnecting it from thecrank 56 by removing the pin 6I. Then by means of a brace 90 (indicatedby dotted lines in Fig. 6) and applied between the shoes 47 'and thedownturned sides of the shell' 62 the said shoe is.

held downward, so that it will form a continuous furrow. Also by meansof a pin 91, passed through the cut-`oif blade 5l, back of the shoe 47,or by some other suitable device, the said blade 5l is held open againstthe action of its spring 54, as indicated in Fig. 6. rlhese adjustmentshaving been effected, the machine is adapted for planting fodder-corn.
